No prob,glad I can share this with people.BTW,For some reason Only SM 1.1 and 3.0 Are supported and NOT 2.0 at least in the demo anyway I hope the final version isnt like this.

If you are using a NV4x card .. it make sense for the game to go for SM3.0 by defualt . but for comparsions sake .. yeah a SM2.0 option would be good to see if theres any increase in performance when switching from 2.0 to 3.0
